The DPRA is an in chemico method which quantifies the remaining concentration of cysteine- or lysine-containing peptide following 24 hours incubation with the test chemical at 25 +/-2,5ºC. The synthetic peptides contain phenylalanine to aid in the detection. Relative peptide concentration is

The neutral red uptake (NRU) assay provides a quantitative measurement of the number of viable cells. The test is based on the ability of living cells to take up and bind neutral red (NR), a dye which easily penetrates cell membranes via non-ionic diffusion and accumulates in the lysosomes. Dying

The in vitro Alkaline Comet Assay is a microgel electrophoresis technique which allows to measure DNA damage (single and double strand breaks, alkali labile sites, incomplete excision repair sites and cross links) cell by cell. Cells are mixed with 0.8% Low Melting Point Agarose which is spread as a

The Ames test is a short-term bacterial reverse gene mutation assay specifically designed to detect a wide range of chemical substances that can produce genetic damage that leads to permanent gene mutations. The test has been described in detail in OECD TG 471 and employs several histidine dependent

Alkaline comet assay (COM) and Micronucleus test (MN) are well-established cytogenetic tests that are used to detect both immediate damages i.e. DNA fragmentation, and permanent damage which results in micronuclei formation. These techniques are often applied separately or, sometimes, in combination

Peripheral blood mononuclear cells (PBMC) are isolated from the peripheral blood using Ficoll gradient centrifugation. The PBMC are then stained with fluorescently-labelled monoclonal antibodies directed against cell surface or intracellular proteins that can be used to identify specific immune cell
